What will students see and do?

Fort Purbrook is one of two historic forts (along with Fort Widley) that make up the Peter Ashley Activity Centre just north of Portsmouth on the south coast.

The forts date back to the Victorian era, and were built to protect the city of Portsmouth from a French invasion that never happened. Situated on Portsdown Hill, Fort Purbrook offers stunning views over Portsmouth and across Portsmouth Harbour.

Student groups can tour the 19th-century fort, including old barrack rooms, a maze of underground tunnels and the unique Cold War-era bunker that was designed to survive the fallout from a nuclear attack.

A wide range of activities is available as part of a package, with qualified supervision where required. This includes air rifle shooting, archery, indoor climbing and mountain biking (with bike maintenance and workshop skills sessions). Certified instructors and supervisors lead each session.

Outdoor adventure activities for every age group include orienteering, camping, bushcraft, assault course and other activities.
